BACKGROUND

The interaction between cancer and the immune system is complex andmultifaceted. See de Visser et al., Nat. Rev. Cancer (2006) 6:24-37.While many cancer patients appear to develop an anti-tumor immuneresponse, cancers also develop strategies to evade immune detection anddestruction. Recently, immunotherapies have been developed for thetreatment and prevention of cancer and other disorders. Immunotherapyprovides the advantage of cell specificity that other treatmentmodalities lack. As such, methods for enhancing the efficacy of immunebased therapies can be clinically beneficial. Advances in defining themechanisms and molecules that regulate immune responses have providednovel therapeutic targets for treating cancer. For example,costimulatory and coinhibitory molecules play a central role in theregulation of T cell immune responses. However, despite impressivepatient responses to antibody agents targeting these costimulatory andcoinhibitory molecules, including for example anti-PD-1/PD-L1,checkpoint inhibition therapy still fails in many patients. Therefore,as with most cancer therapies, there remains a need for new compositionsand methods that can improve the effectiveness of these agents.

SUMMARY

Accordingly, in various aspects, the present invention provides forcompositions and methods that are useful for cancer immunotherapy, e.g.to manipulate or modify immune signals for therapeutic benefit. Invarious embodiments, the invention reverses or suppresses immuneinhibitory signals while providing immune activating or co-stimulatorysignals in a beneficial context. For instance, in one aspect, thepresent invention provides chimeric protein comprising: (a) a firstextracellular domain of a type I transmembrane protein at or near theN-terminus, (b) a second extracellular domain of a type II transmembraneprotein at or near the C-terminus, and (c) a linker, wherein one of thefirst and second extracellular domains is an immune inhibitory signaland one of the first and second extracellular domains is an immunestimulatory signal. By linking these two molecules in a functionalorientation, coordination between the positive and negative signals canbe achieved. For example, the present invention provides, in variousembodiments, masking of negative immune signals and stimulation ofpositive immune signals in a single construct. In various embodiments,provides for compositions that are not antibodies, or based uponantibody-derived antigen binding domains (e.g. complementaritydetermining regions, CDRs), but rather provide direct receptor/ligandinteraction.

In cancer patients, an immune response can be stimulated against tumorantigens to activate a patient's own immune system to kill tumor cells.However, some cancer cells devise strategies to evade an immune responsein a process known as immuno-editing. This can include down-regulationof specific antigens, down-regulation of MHC I, up-regulation of immuneregulatory surface molecules (PD-L1, PD-L2, CEACAM1, galectin-9, B7-H3,B7-H4, VISTA, CD47, etc.) or up-regulation of soluble immune inhibitorymolecules (IDO, TGF-β, MICA, etc). In general, these strategies areco-opted by tumor cells so that when tumor-infiltrating immune killercells encounter a tumor cell, those cells become directly inhibited byimmunosuppressive factors and therefore cannot kill the tumor cell. Manyof the immunosuppressive ligands co-opted by tumor cells to suppress animmune response interact with receptors that are type I membraneproteins. In some embodiments, the chimeric protein of the presentinvention comprises an extracellular domain of an immune inhibitoryagent, including without limitation, one or more of TIM-3, BTLA, PD-1,CTLA-4, B7-H4, PD-L1, PD-L2, B7-H3, CD244, TIGIT, CD172a/SIRPα,VISTA/VSIG8, CD115, CD200, CD223, and TMIGD2. In some embodiments, thechimeric protein of the present invention comprises an extracellulardomain of a type I membrane protein which has immune inhibitoryproperties. In various embodiments, the chimeric protein is engineeredto disrupt, block, reduce, and/or inhibit the transmission of an immuneinhibitory signal, by way of non-limiting example, the binding of PD-1with PD-L1 or PD-L2 and/or the binding of CD172a with CD47 and/or thebinding of TIM-3 with one or more of galectin-9 and/orphosphatidylserine.

Further, in addition to suppression of immune inhibitory signaling, itis often desirable to enhance immune stimulatory signal transmission toboost an immune response, for instance to enhance a patient's anti-tumorimmune response. In some embodiments, the chimeric protein of thepresent invention comprises an extracellular domain of an immunestimulatory signal, which, without limitation, is one or more of OX-40ligand, LIGHT (CD258), GITR ligand, CD70, CD30 ligand, CD40 ligand,CD137 ligand, TRAIL and TL1A. In some embodiments, the chimeric proteinof the present invention comprises an extracellular domain of a type IImembrane protein which has immune stimulatory properties. In variousembodiments, the chimeric protein is engineered to enhance, increase,and/or stimulate the transmission of an immune stimulatory signal, byway of non-limiting example, the binding of GITR with one or more ofGITR ligand and/or the binding of OX40 with OX40L and/or CD40 with CD40ligand.

In various embodiments, the chimeric protein comprises an immuneinhibitory receptor extracellular domain and an immune stimulatoryligand extracellular domain which can, without limitation, deliver animmune stimulation to a T cell while masking a tumor cell's immuneinhibitory signals. In various embodiments, the present chimericproteins provide improved immunotherapeutic benefits by effectivelycausing the substitution of an immune inhibitory signal for an immunestimulatory signal. For example, a chimeric protein construct comprising(i) the extracellular domain of PD-1 and (ii) extracellular domain ofOX40L, allows for the disruption of an inhibitory PD-L1/L2 signal andits replacement with a stimulating OX40L. Accordingly, the presentchimeric proteins, in some embodiments are capable of, or find use inmethods involving, reducing or eliminating an inhibitory immune signaland/or increasing or activating an immune stimulatory signal. Suchbeneficial properties are enhanced by the single construct approach ofthe present chimeric proteins. For instance, the signal replacement canbe effected nearly simultaneously and the signal replacement is tailoredto be local at a site of clinical importance (e.g. the tumormicroenvironment). Further embodiments apply the same principle to otherchimeric protein constructs, such as, for example, (i) the extracellulardomain of PD-1 and (ii) extracellular domain of GITRL; (i) theextracellular domain of BTLA and (ii) extracellular domain of OX40L; (i)the extracellular domain of TIGIT and (ii) extracellular domain ofOX40L; (i) the extracellular domain of TMIGD2 and (ii) extracellulardomain of OX40L; (i) the extracellular domain of TIM3 and (ii)extracellular domain of OX40L; and (i) the extracellular domain ofCD172a or CD115 and (ii) extracellular domain of CD40L; among others.

Further still, in some embodiments, the present chimeric proteins arecapable of, or find use in methods involving, shifting the balance ofimmune cells in favor of immune attack of a tumor. For instance, thepresent chimeric proteins can shift the ratio of immune cells at a siteof clinical importance in favor of cells that can kill a tumor (e.g. Tcells, cytotoxic T lymphocytes, T helper cells, natural killer (NK)cells, natural killer T (NKT) cells, anti-tumor macrophages (e.g. M1macrophages), B cells, and dendritic cells and in opposition to cellsthat protect tumors (e.g. myeloid-derived suppressor cells (MDSCs),regulatory T cells (Tregs); tumor associated neutrophils (TANs), M2macrophages, and tumor associated macrophages (TAMs)). In someembodiments, the present chimeric protein is capable of increasing aratio of effector T cells to regulatory T cells.

In various embodiments, the present chimeric protein unexpectedlyprovides binding of the extracellular domain components to theirrespective binding partners with longer off rates (Kd or K_(off)) andtherefore, inter alia, accords longer occupancy of the receptor toligand and vice versa. For instance, in some embodiments, this providesa sustained negative signal masking effect. Further, in someembodiments, this delivers a longer positive signal effect, e.g. toallow an effector cell to be adequately stimulated (e.g. forproliferation and/or release of stimulatory signals like cytokines).Also, this stable synapse of cells (e.g. a tumor cell bearing negativesignals and a T cell which could attack the tumor) provides spatialorientation to favor tumor reduction—such as positioning the T cells toattack tumor cells and/or sterically preventing the tumor cell fromdelivering negative signals, including negative signals beyond thosemasked by the chimeric protein of the invention. In still furtherembodiments, this provides longer on-target (e.g. intra-tumoral)half-life (t_(1/2)) as compared to serum t_(1/2) of the chimericproteins. Such properties could have the combined advantage of reducingoff-target toxicities associated with systemic distribution of thechimeric proteins.

Also in various aspects, the present chimeric protein is used in amethod for treating cancer comprising administering an effective amountof a pharmaceutical composition comprising the chimeric protein to apatient in need thereof. In further aspects, the present chimericprotein is used in a method for treating infections, including withoutlimitation, viral infections or other intracellular pathogens. In stillfurther aspects, the present chimeric protein is used in a method fortreating autoimmune diseases.

BRIEF DESCRIPTION OF THE FIGURES

FIG. 1 shows illustrations of orientations of type I (left) and type II(right) membrane proteins in a cell membrane. In the type I membraneprotein of the left panel, the amino terminus (denoted “N”) faces theextracellular environment and the carboxy terminus (denoted “C”) islocalized to the intracellular environment. In contrast, the type IImembrane protein of the right panel is characterized by an extracellularfacing carboxy terminus and an amino terminus in the intracellularspace.

FIG. 2 shows immune inhibitory and immune stimulatory signaling that isrelevant to the present invention (from Mahoney, Nature Reviews DrugDiscovery 2015:14; 561-585).

FIG. 3A to FIG. 3D show a schematic illustration of how a type I andtype II membrane protein (FIG. 3A) may be engineered with transmembraneand intracellular domains removed (FIG. 3B) and adjoined using a linkersequence (FIG. 3C) to generate a single fusion protein wherein theextracellular domains of the type I and type II membrane proteins eachface outward in a single fusion protein (FIG. 3D). FIG. 3C depicts thelinkage of a type I and type II membrane protein by removal of thetransmembrane and intracellular domains of each protein, and where theliberated extracellular domains (ECD) from each protein have beenadjoined by a linker sequence. The ECD in this depiction may include theentire amino acid sequence of a candidate type I or type II proteinwhich is typically localized outside the cell membrane, or any portionthereof which retains binding to the intended receptor or ligand. FIG.3D depicts adjoined extracellular domains in a linear construct whereinthe extracellular domain of the type I membrane protein faces the ‘left’side of the construct and the extracellular domain of the type IImembrane protein faces the “right” side of the construct.

FIG. 4A to FIG. 4C show that tumor cells may express PD-L1 on the cellsurface (FIG. 4A), which can bind to PD-1 expressed by a T cell (FIG.4B). This interaction suppresses activation of T cells. A fusion proteinof the extracellular domain of PD-1, adjoined to the extracellulardomain of OX40L may bind to PD-L1 on the surface of a tumor cell,preventing binding to PD-1 on the surface of a T cell (FIG. 4C). Thefusion protein may then ‘dangle’ from the surface of the tumor cell, andthe OX40L portion of the fusion protein may then bind to OX40 expressedon the surface of the T cell. This would result in replacement of aninhibitory PD-L1 signal with a co-stimulatory OX40L signal to enhancethe anti-tumor activity of T cells.

FIG. 7A shows a schematic representation ofthe ELISA method used to detect binding of mPD-1-Fc-OX40L to mPD-L1.Recombinant mPD-L1 fused to human Fc (mPD-L1-hFc) was used to capturethe mPD-1-Fc-OX40L chimeric protein in the culture media. A horseradishperoxidase (HRP)-conjugated polyclonal antibody to mouse IgG (H+L) wasused for the detection of the bound proteins. FIG. 7B shows results inwhich two-fold serial dilutions of CHO-K1 culture media containingmPD-1-Fc-OX40L protein was incubated with plate-bound mPD-L1-hFc andbinding was measured by absorbance at 450 nm. mPD-1-Fc proteincontaining culture media was used as a positive control and media alonewas used as a negative control.

DETAILED DESCRIPTION

The present invention is based, in part, on the discovery that chimericproteins can be engineered from the extracellular, or effector, regionsof immune-modulating transmembrane proteins in a manner that exploitsthe orientations of these proteins (e.g. type I versus type II) andtherefore allows the delivery of immune stimulatory and/or immuneinhibitory signals, including, for example, masking an immune inhibitorysignal and replacing it with an immune stimulatory signal in thetreatment of cancer.

Chimeric Proteins

In one aspect, the present invention relates to a chimeric proteincomprising: (a) a first extracellular domain of a type I transmembraneprotein at or near the N-terminus, (b) a second extracellular domain ofa type II transmembrane protein at or near the C-terminus, and (c) alinker, wherein one of the first and second extracellular domains is animmune inhibitory signal and one of the first and second extracellulardomains is an immune stimulatory signal.

In some embodiments, chimeric protein refers to a recombinant fusionprotein, e.g. a single polypeptide having the extracellular domainsdescribed herein (and, optionally a linker). For example, in variousembodiments, the chimeric protein is translated as a single unit in acell. In some embodiments, chimeric protein refers to a recombinantprotein of multiple polypeptides, e.g. multiple extracellular domainsdescribed herein, that are linked to yield a single unit, e.g. in vitro(e.g. with one or more synthetic linkers described herein).

In some embodiments, an extracellular domain refers to a portion of atransmembrane protein which is capable of interacting with theextracellular environment. In various embodiments, an extracellulardomain refers to a portion of a transmembrane protein which issufficient to bind to a ligand or receptor and effective transmit asignal to a cell. In various embodiments, an extracellular domain is theentire amino acid sequence of a transmembrane protein which is externalof a cell or the cell membrane. In various embodiments, an extracellulardomain is the that portion of an amino acid sequence of a transmembraneprotein which is external of a cell or the cell membrane and is neededfor signal transduction and/or ligand binding as may be assayed usingmethods know in the art (e.g. in vitro ligand binding and/or cellularactivation assays).

In some embodiments, an immune inhibitory signal refers to a signal thatdiminishes or eliminates an immune response. For example, in the contextof oncology, such signals may diminish or eliminate antitumor immunity.Under normal physiological conditions, inhibitory signal are useful inthe maintenance of self-tolerance (e.g. prevention of autoimmunity) andalso to protect tissues from damage when the immune system is respondingto pathogenic infection. For instance, without limitation, immuneinhibitory signal may be identified by detecting an increase in cellularproliferation, cytokine production, cell killing activity or phagocyticactivity when such an inhibitory signal is blocked. Specific examplessuch inhibitory signals include blockade of PD-1 of PD-L1/L2 usingantibody mediated blockade or through competitive inhibition of PD-L1/L2using PD-1 containing fusion proteins. When such an inhibitory signal isblocked through inhibition of PD-L1/L2, it leads to enhance tumorkilling activity by T cells because they are no longer being inhibitedby PD-L1 or PD-L2. In another example, and inhibitory signal may beprovided by CD47 to macrophages expressing CD172a. Binding of CD47 toCD172a typically inhibits the ability of a macrophage to phagocytose atarget cell, which can be restored through blockade of CD47 withblocking antibodies or through competitive inhibition of CD47 usingCD172a containing fusion proteins.

In some embodiments, an immune stimulatory signal refers to a signalthat enhances an immune response. For example, in the context ofoncology, such signals may enhance antitumor immunity. For instance,without limitation, immune stimulatory signal may be identified bydirectly stimulating proliferation, cytokine production, killingactivity or phagocytic activity of leukocytes. Specific examples includedirect stimulation of TNF superfamily receptors such as OX40, 4-1BB orTNFRSF25 using either receptor agonist antibodies or using fusionproteins encoding the ligands for such receptors (OX40L, 4-1BBL, TL1A,respectively). Stimulation from any one of these receptors may directlystimulate the proliferation and cytokine production of individual T cellsubsets. Another example includes direct stimulation of an immuneinhibitory cell with through a receptor that inhibits the activity ofsuch an immune suppressor cell. This would include, for example,stimulation of CD4+FoxP3+ regulatory T cells with a GITR agonistantibody or GITRL containing fusion protein, which would reduce theability of those regulatory T cells to suppress the proliferation ofconventional CD4+ or CD8+ T cells. In another example, this wouldinclude stimulation of CD40 on the surface of an antigen presenting cellusing a CD40 agonist antibody or a fusion protein containing CD40L,causing activation of antigen presenting cells including enhancedability of those cells to present antigen in the context of appropriatenative costimulatory molecules, including those in the B7 or TNFsuperfamily.

Membrane proteins typically consist of an extracellular domain, one or aseries of trans-membrane domains, and an intracellular domain. Withoutwishing to be bound by theory, the extracellular domain of a membraneprotein is responsible for interacting with a soluble or membrane boundreceptor or ligand. Without wishing to be bound by theory, thetrans-membrane domain(s) are responsible for localizing a protein to theplasma membrane. Without wishing to be bound by theory, theintracellular domain of a membrane protein is responsible forcoordinating interactions with cellular signaling molecules tocoordinate intracellular responses with the extracellular environment(or visa-versa). There are two types of single-pass membrane proteins,those with an extracellular amino terminus and intracellular carboxyterminus (type I) and those with an extracellular carboxy terminus andintracellular amino terminus (type II). Both type I and type II membraneproteins can be either receptors or ligands. For type I membraneproteins, the amino terminus of the protein faces outside the cell, andtherefore contains the functional domains that are responsible forinteracting with other binding partners (either ligands or receptors) inthe extracellular environment (FIG. 1 , left image). For type IImembrane proteins, the carboxy terminus of the protein faces outside thecell, and therefore contains the functional domains that are responsiblefor interacting with other binding partners (either ligands orreceptors) in the extracellular environment (FIG. 1 , right image).Thus, these two types of proteins have opposite orientations to eachother.

Because the outward facing domains of type I and type II membraneproteins are opposite (FIG. 1 ), it is possible to link theextracellular domains of a type I and type II membrane protein such thatthe ‘outward facing’ domains of the molecules are also in opposingorientation to each other (FIG. 3 ). The resulting construct wouldtherefore consist of the extracellular domain of a type I membraneprotein on the ‘left’ side of the molecule, connected to theextracellular domain of a type II membrane protein on the ‘right’ sideof the molecule using a linker sequence. This construct could beproduced by cloning of these three fragments (the extracellular domainof a type I protein, followed by a linker sequence, followed by theextracellular domain of a type II protein) into a vector (plasmid, viralor other) wherein the amino terminus of the complete sequencecorresponded to the ‘left’ side of the molecule containing the type Iprotein and the carboxy terminus of the complete sequence correspondedto the ‘right’ side of the molecule containing the type II protein.Accordingly, in various embodiments, the present chimeric proteins areengineered as such.

In some embodiments, the extracellular domain may be used to produce asoluble protein to competitively inhibit signaling by that receptor'sligand. In some embodiments, the extracellular domain may be used toprovide artificial signaling.

In some embodiments, the extracellular domain of a type I transmembraneprotein is an immune inhibitory signal. In some embodiments, theextracellular domain of a type II transmembrane protein is an immunestimulatory signal.

In various embodiments, the chimeric protein may comprise an amino acidsequence having one or more amino acid mutations relative to any of theprotein sequences described herein. In some embodiments, the one or moreamino acid mutations may be independently selected from substitutions,insertions, deletions, and truncations.

In some embodiments, the amino acid mutations are amino acidsubstitutions, and may include conservative and/or non-conservativesubstitutions.

“Conservative substitutions” may be made, for instance, on the basis ofsimilarity in polarity, charge, size, solubility, hydrophobicity,hydrophilicity, and/or the amphipathic nature of the amino acid residuesinvolved. The 20 naturally occurring amino acids can be grouped into thefollowing six standard amino acid groups: (1) hydrophobic: Met, Ala,Val, Leu, Ile; (2) neutral hydrophilic: Cys, Ser, Thr; Asn, Gln; (3)acidic: Asp, Glu; (4) basic: His, Lys, Arg; (5) residues that influencechain orientation: Gly, Pro; and (6) aromatic: Trp, Tyr, Phe.

As used herein, “conservative substitutions” are defined as exchanges ofan amino acid by another amino acid listed within the same group of thesix standard amino acid groups shown above. For example, the exchange ofAsp by Glu retains one negative charge in the so modified polypeptide.In addition, glycine and proline may be substituted for one anotherbased on their ability to disrupt α-helices.

As used herein, “non-conservative substitutions” are defined asexchanges of an amino acid by another amino acid listed in a differentgroup of the six standard amino acid groups (1) to (6) shown above.

In various embodiments, the substitutions may also include non-classicalamino acids (e.g. selenocysteine, pyrrolysine, N-formylmethionineβ-alanine, GABA and δ-Aminolevulinic acid, 4-aminobenzoic acid (PABA),D-isomers of the common amino acids, 2,4-diaminobutyric acid, α-aminoisobutyric acid, 4-aminobutyric acid, Abu, 2-amino butyric acid, γ-Abu,ε-Ahx, 6-amino hexanoic acid, Aib, 2-amino isobutyric acid, 3-aminopropionic acid, ornithine, norleucine, norvaline, hydroxyproline,sarcosme, citrulline, homocitrulline, cysteic acid, t-butylglycine,t-butylalanine, phenylglycine, cyclohexylalanine, β-alanine,fluoro-amino acids, designer amino acids such as β methyl amino acids, Cα-methyl amino acids, N α-methyl amino acids, and amino acid analogs ingeneral).

Mutations may also be made to the nucleotide sequences of the chimericproteins by reference to the genetic code, including taking into accountcodon degeneracy.

In various embodiments, the chimeric protein comprises a linker. Invarious embodiments, the linker may be derived from naturally-occurringmulti-domain proteins or are empirical linkers as described, forexample, in Chichili et al., (2013), Protein Sci. 22(2):153-167, Chen etal., (2013), Adv Drug Deliv Rev. 65(10):1357-1369, the entire contentsof which are hereby incorporated by reference. In some embodiments, thelinker may be designed using linker designing databases and computerprograms such as those described in Chen et al., (2013), Adv Drug DelivRev. 65(10):1357-1369 and Crasto et. al., (2000), Protein Eng.13(5):309-312, the entire contents of which are hereby incorporated byreference.

In some embodiments, the linker is a synthetic linker such as PEG.

In other embodiments, the linker is a polypeptide. In some embodiments,the linker is less than about 500 amino acids long, about 450 aminoacids long, about 400 amino acids long, about 350 amino acids long,about 300 amino acids long, about 250 amino acids long, about 200 aminoacids long, about 150 amino acids long, or about 100 amino acids long.For example, the linker may be less than about 100, about 95, about 90,about 85, about 80, about 75, about 70, about 65, about 60, about 55,about 50, about 45, about 40, about 35, about 30, about 25, about 20,about 19, about 18, about 17, about 16, about 15, about 14, about 13,about 12, about 11, about 10, about 9, about 8, about 7, about 6, about5, about 4, about 3, or about 2 amino acids long. In some embodiments,the linker is flexible. In another embodiment, the linker is rigid.

In various embodiments, the linker is substantially comprised of glycineand serine residues (e.g. about 30%, or about 40%, or about 50%, orabout 60%, or about 70%, or about 80%, or about 90%, or about 95%, orabout 97% glycines and serines).

In various embodiments, the linker is a hinge region of an antibody(e.g., of IgG, IgA, IgD, and IgE, inclusive of subclasses (e.g. IgG1,IgG2, IgG3, and IgG4, and IgA1 and IgA2)). The hinge region, found inIgG, IgA, IgD, and IgE class antibodies, acts as a flexible spacer,allowing the Fab portion to move freely in space. In contrast to theconstant regions, the hinge domains are structurally diverse, varying inboth sequence and length among immunoglobulin classes and subclasses.For example, the length and flexibility of the hinge region varies amongthe IgG subclasses. The hinge region of IgG1 encompasses amino acids216-231 and, because it is freely flexible, the Fab fragments can rotateabout their axes of symmetry and move within a sphere centered at thefirst of two inter-heavy chain disulfide bridges. IgG2 has a shorterhinge than IgG1, with 12 amino acid residues and four disulfide bridges.The hinge region of IgG2 lacks a glycine residue, is relatively short,and contains a rigid poly-proline double helix, stabilized by extrainter-heavy chain disulfide bridges. These properties restrict theflexibility of the IgG2 molecule. IgG3 differs from the other subclassesby its unique extended hinge region (about four times as long as theIgG1 hinge), containing 62 amino acids (including 21 prolines and 11cysteines), forming an inflexible poly-proline double helix. In IgG3,the Fab fragments are relatively far away from the Fc fragment, givingthe molecule a greater flexibility. The elongated hinge in IgG3 is alsoresponsible for its higher molecular weight compared to the othersubclasses. The hinge region of IgG4 is shorter than that of IgG1 andits flexibility is intermediate between that of IgG1 and IgG2. Theflexibility of the hinge regions reportedly decreases in the orderIgG3>IgG1>IgG4>IgG2. In other embodiments, the linker may be derivedfrom human IgG4 and contain one or more mutations to enhancedimerization (including S228P) or FcRn binding.

According to crystallographic studies, the immunoglobulin hinge regioncan be further subdivided functionally into three regions: the upperhinge region, the core region, and the lower hinge region. See Shin etal., 1992 Immunological Reviews 130:87. The upper hinge region includesamino acids from the carboxyl end of C_(H1) to the first residue in thehinge that restricts motion, generally the first cysteine residue thatforms an interchain disulfide bond between the two heavy chains. Thelength of the upper hinge region correlates with the segmentalflexibility of the antibody. The core hinge region contains theinter-heavy chain disulfide bridges, and the lower hinge region joinsthe amino terminal end of the C_(H2) domain and includes residues inC_(H2). Id. The core hinge region of wild-type human IgG1 contains thesequence Cys-Pro-Pro-Cys which, when dimerized by disulfide bondformation, results in a cyclic octapeptide believed to act as a pivot,thus conferring flexibility. In various embodiments, the present linkercomprises, one, or two, or three of the upper hinge region, the coreregion, and the lower hinge region of any antibody (e.g., of IgG, IgA,IgD, and IgE, inclusive of subclasses (e.g. IgG1, IgG2, IgG3, and IgG4,and IgA1 and IgA2)). The hinge region may also contain one or moreglycosylation sites, which include a number of structurally distincttypes of sites for carbohydrate attachment. For example, IgA1 containsfive glycosylation sites within a 17-amino-acid segment of the hingeregion, conferring resistance of the hinge region polypeptide tointestinal proteases, considered an advantageous property for asecretory immunoglobulin. In various embodiments, the linker of thepresent invention comprises one or more glycosylation sites.

In various embodiments, the linker comprises an Fc domain of an antibody(e.g., of IgG, IgA, IgD, and IgE, inclusive of subclasses (e.g. IgG1,IgG2, IgG3, and IgG4, and IgA1 and IgA2)). In various embodiments, thelinker comprises a hinge-CH2-CH3 Fc domain derived from a human IgG4antibody. In various embodiments, the linker comprises a hinge-CH2-CH3Fc domain derived from a human IgG1 antibody. In some embodiments, theFc domain exhibits increased affinity for and enhanced binding to theneonatal Fc receptor (FcRn). In some embodiments, the Fc domain includesone or more mutations that increases the affinity and enhances bindingto FcRn. Without wishing to be bound by theory, it is believed thatincreased affinity and enhanced binding to FcRn increases the in vivohalf-life of the present chimeric proteins.

In some embodiments, the Fc domain linker contains one or more aminoacid substitutions at amino acid residue 250, 252, 254, 256, 308, 309,311, 428, 433 or 434 (in accordance with Kabat numbering), orequivalents thereof.

In an embodiment, the aminoacid substitution at amino acid residue 387 is a substitution witharginine, proline, histidine, serine, threonine, or alanine. In anembodiment, the amino acid substitution at amino acid residue 389 is asubstitution with proline, serine or asparagine. In an embodiment, theamino acid substitution at amino acid residue 428 is a substitution withleucine. In an embodiment, the amino acid substitution at amino acidresidue 433 is a substitution with arginine, serine, isoleucine,proline, or glutamine. In an embodiment, the amino acid substitution atamino acid residue 434 is a substitution with histidine, phenylalanine,or tyrosine.

In some embodiments, the Fc domain linker (e.g., comprising an IgGconstant region) comprises one or more mutations such as substitutionsat amino acid residue 252, 254, 256, 433, 434, or 436 (in accordancewith Kabat numbering). In an embodiment, the IgG constant regionincludes a triple M252Y/S254T/T256E mutation or YTE mutation. In anotherembodiment, the IgG constant region includes a triple H433K/N434F/Y436Hmutation or KFH mutation.

In various embodiments, the linker may be functional. For example,without limitation, the linker may function to improve the foldingand/or stability, improve the expression, improve the pharmacokinetics,and/or improve the bioactivity of the present chimeric protein. Inanother example, the linker may function to target the chimeric proteinto a particular cell type or location.

In various embodiments, the present chimeric proteins are capable of,and can be used in methods comprising, promoting immune activation (e.g.against tumors). In various embodiments, the present chimeric proteinsare capable of, and can be used in methods comprising, suppressingimmune inhibition (e.g. that allows tumors to survive). In variousembodiments, the present chimeric proteins provide improved immuneactivation and/or improved suppression of immune inhibition due to theproximity of signaling that is provided by the chimeric nature of theconstructs.

In various embodiments, the present chimeric proteins are capable of, orcan be used in methods comprising, modulating the amplitude of an immuneresponse, e.g. modulating the level of effector output. In someembodiments, e.g. when used for the treatment of cancer, the presentchimeric proteins alter the extent of immune stimulation as compared toimmune inhibition to increase the amplitude of a T cell response,including, without limitation, stimulating increased levels of cytokineproduction, proliferation or target killing potential.

In various embodiments the present chimeric proteins, in someembodiments are capable of, or find use in methods involving, masking aninhibitory ligand on the surface of a tumor cell and replacing thatimmune inhibitory ligand with an immune stimulatory ligand (see, e.g.FIG. 4 ). For example, a chimeric protein construct comprising (i) theextracellular domain of PD-1 and (ii) extracellular domain of OX40L,allows for the disruption of an inhibitory PD-L1 signal and replacing itwith a stimulating OX40L. Accordingly, the present chimeric proteins, insome embodiments are capable of, or find use in methods involving,reducing or eliminating an inhibitory immune signal and/or increasing oractivating an immune stimulatory signal. For example, a tumor cellbearing an inhibitory signal (and thus evading an immune response) maybe substituted for a positive signal binding on a T cell that can thenattack a tumor cell. Accordingly, in some embodiments, an inhibitoryimmune signal is masked by the present constructs and a stimulatoryimmune signal is activated. Such beneficial properties are enhanced bythe single construct approach of the present chimeric proteins. Forinstance, the signal replacement can be effected nearly simultaneouslyand the signal replacement is tailored to be local at a site of clinicalimportance (e.g. the tumor microenvironment). Further embodiments applythe same principle to other chimeric protein constructs, such as, forexample, (i) the extracellular domain of PD-1 and (ii) extracellulardomain of GITRL; (i) the extracellular domain of BTLA and (ii)extracellular domain of OX40L; (i) the extracellular domain of TIGIT and(ii) extracellular domain of OX40L; (i) the extracellular domain of TIM3and (ii) extracellular domain of OX40L; and (i) the extracellular domainof CD172a and (ii) extracellular domain of CD40L; and (i) theextracellular domain of CD115 and (ii) extracellular domain of CD40L;and (i) the extracellular domain of TIM3 and (ii) extracellular domainof OX40L; and (i) the extracellular domain of TIGIT and (ii)extracellular domain of OX40L; among others.

In various embodiments, the present chimeric protein increasesand/or stimulates GITR and/or the binding of GITR with one or more ofGITR ligand. In various embodiments, the present chimeric proteinincreases and/or stimulates OX40 and/or the binding of OX40 with one ormore of OX40 ligand.

In other embodiments, the present chimeric proteins are capable of, orfind use in methods involving, enhancing, restoring, promoting and/orstimulating immune modulation. In some embodiments, the present chimericproteins described herein, restore, promote and/or stimulate theactivity or activation of one or more immune cells against tumor cellsincluding, but not limited to: T cells, cytotoxic T lymphocytes, Thelper cells, natural killer (NK) cells, natural killer T (NKT) cells,anti-tumor macrophages (e.g. M1 macrophages), B cells, and dendriticcells.

In some embodiments, the present therapies mayalter the ratio of M1 versus M2 macrophages in the tumor site and/or TMEto favor M1 macrophages.

In various embodiments, the present chimeric proteins are capable of,and can be used in methods comprising, inhibiting and/or reducing T cellinactivation and/or immune tolerance to a tumor, comprisingadministering an effective amount of a chimeric protein described hereinto a subject. In some embodiments, the present chimeric proteins areable to increase the serum levels of various cytokines including, butnot limited to, one or more of IFNγ, TNFα, IL-2, IL-4, IL-5, IL-6, IL-9,IL-10, IL-13, IL-17A, IL-17F, and IL-22.

Detection of such a cytokine response mayprovide a method to determine the optimal dosing regimen for theindicated chimeric fusion protein (see, e.g. FIG. 11K).

In various embodiments, the present chimeric proteins inhibit, blockand/or reduce cell death of an anti-tumor CD8+ and/or CD4+ T cell; orstimulate, induce, and/or increase cell death of a pro-tumor T cell. Tcell exhaustion is a state of T cell dysfunction characterized byprogressive loss of proliferative and effector functions, culminating inclonal deletion. Accordingly, a pro-tumor T cell refers to a state of Tcell dysfunction that arises during many chronic infections and cancer.This dysfunction is defined by poor proliferative and/or effectorfunctions, sustained expression of inhibitory receptors and atranscriptional state distinct from that of functional effector ormemory T cells. Exhaustion prevents optimal control of infection andtumors. In addition, an anti-tumor CD8+ and/or CD4+ T cell refers to Tcells that can mount an immune response to a tumor. Illustrativepro-tumor T cells include, but are not limited to, Tregs, CD4+ and/orCD8+ T cells expressing one or more checkpoint inhibitory receptors, Th2cells and Th17 cells. Checkpoint inhibitory receptors refers toreceptors (e.g. CTLA-4, B7-H3, B7-H4, TIM-3) expressed on immune cellsthat prevent or inhibit uncontrolled immune responses.

In various embodiments, the present chimeric proteins are capable of,and can be used in methods comprising, transiently stimulating effectorT cells for no longer than about 12 hours, about 24 hours, about 48hours, about 72 hours or about 96 hours or about 1 week or about 2weeks. In various embodiments, the present chimeric proteins are capableof, and can be used in methods comprising, transiently depleting orinhibiting regulatory T cells for no longer than about 12 hours, about24 hours, about 48 hours, about 72 hours or about 96 hours or about 1week or about 2 weeks. In various embodiments, the transient stimulationof effector T cells and/or transient depletion or inhibition ofregulatory T cells occurs substantially in a patient's bloodstream or ina particular tissue/location including lymphoid tissues such as forexample, the bone marrow, lymph-node, spleen, thymus, mucosa-associatedlymphoid tissue (MALT), non-lymphoid tissues, or in the tumormicroenvironment.

In various embodiments, the present chimeric proteins provide advantagesincluding, without limitation, ease of use and ease of production. Thisis because two distinct immunotherapy agents are combined into a singleproduct which allows for a single manufacturing process instead of twoindependent manufacturing processes. In addition, administration of asingle agent instead of two separate agents allows for easieradministration and greater patient compliance. Further, in contrast to,for example, monoclonal antibodies, which are large multimeric proteinscontaining numerous disulfide bonds and post-translational modificationssuch as glycosylation, the present chimeric proteins are easier and morecost effective to manufacture.

In various embodiments, the present chimeric protein is producible in amammalian host cell as a secretable and fully functional singlepolypeptide chain (see, e.g., FIG. 13A, FIGS. 17E-17H, FIGS. 17N-17S).

In various embodiments, the present chimeric protein unexpectedlyprovides binding of the extracellular domain components to theirrespective binding partners with slow off rates (Kd or K_(off)). In someembodiments, this provides an unexpectedly long interaction of thereceptor to ligand and vice versa. Such an effect allows for a sustainednegative signal masking effect (see, e.g., FIGS. 14A-14O, FIGS.17I-17M). Further, in some embodiments, this delivers a longer positivesignal effect, e.g. to allow an effector cell to be adequatelystimulated for an anti-tumor effect. For example, the present chimericprotein, e.g. via the long off rate binding allows sufficient signaltransmission to provide T cell proliferation and allow for anti-tumorattack. By way of further example, the present chimeric protein, e.g.via the long off rate binding allows sufficient signal transmission toprovide release of stimulatory signals, such as, for example, cytokinesAlso. The stable synapse of cells promoted by the present agents (e.g. atumor cell bearing negative signals and a T cell which could attack thetumor) provides spatial orientation to favor tumor reduction—such aspositioning the T cells to attack tumor cells and/or stericallypreventing the tumor cell from delivering negative signals, includingnegative signals beyond those masked by the chimeric protein of theinvention.

In some embodiments, this provides longer on-target (e.g. intra-tumoral)half-life (t_(1/2)) as compared to serum t_(1/2) of the chimericproteins. Such properties could have the combined advantage of reducingoff-target toxicities associated with systemic distribution of thechimeric proteins (see, e.g., FIGS. 14M-14O).

Further, in various embodiments, the present chimeric proteins providesynergistic therapeutic effects as it allows for improved site-specificinterplay of two immunotherapy agents. In some embodiments, the presentchimeric proteins provide the potential for reducing off-site and/orsystemic toxicity.

Diseases; Methods of Treatment, and Patient Selections

In various embodiments, the present invention pertains to cancers and/ortumors; for example, the treatment or prevention of cancers and/ortumors. As described elsewhere herein, the treatment of cancer mayinvolve in various embodiments, modulating the immune system with thepresent chimeric proteins to favor immune stimulation over immuneinhibition.

Cancers or tumors refer to an uncontrolled growth of cells and/orabnormal increased cell survival and/or inhibition of apoptosis whichinterferes with the normal functioning of the bodily organs and systems.Included are benign and malignant cancers, polyps, hyperplasia, as wellas dormant tumors or micrometastases. Also, included are cells havingabnormal proliferation that is not impeded by the immune system (e.g.virus infected cells). The cancer may be a primary cancer or ametastatic cancer. The primary cancer may be an area of cancer cells atan originating site that becomes clinically detectable, and may be aprimary tumor. In contrast, the metastatic cancer may be the spread of adisease from one organ or part to another non-adjacent organ or part.The metastatic cancer may be caused by a cancer cell that acquires theability to penetrate and infiltrate surrounding normal tissues in alocal area, forming a new tumor, which may be a local metastasis. Thecancer may also be caused by a cancer cell that acquires the ability topenetrate the walls of lymphatic and/or blood vessels, after which thecancer cell is able to circulate through the bloodstream (thereby beinga circulating tumor cell) to other sites and tissues in the body. Thecancer may be due to a process such as lymphatic or hematogenous spread.The cancer may also be caused by a tumor cell that comes to rest atanother site, re-penetrates through the vessel or walls, continues tomultiply, and eventually forms another clinically detectable tumor. Thecancer may be this new tumor, which may be a metastatic (or secondary)tumor.

The cancer may be caused by tumor cells that have metastasized, whichmay be a secondary or metastatic tumor. The cells of the tumor may belike those in the original tumor. As an example, if a breast cancer orcolon cancer metastasizes to the liver, the secondary tumor, whilepresent in the liver, is made up of abnormal breast or colon cells, notof abnormal liver cells.

In one embodiment, for instance in thetreatment of cancer, the chimeric protein (and/or additional agents) areadministered in the tumor microenvironment (e.g. cells, molecules,extracellular matrix and/or blood vessels that surround and/or feed atumor cell, inclusive of, for example, tumor vasculature;tumor-infiltrating lymphocytes; fibroblast reticular cells; endothelialprogenitor cells (EPC); cancer-associated fibroblasts; pericytes; otherstromal cells; components of the extracellular matrix (ECM); dendriticcells; antigen presenting cells; T-cells; regulatory T cells;macrophages; neutrophils; and other immune cells located proximal to atumor) or lymph node and/or targeted to the tumor microenvironment orlymph node. In various embodiments, for instance in the treatment ofcancer, the chimeric protein (and/or additional agents) are administeredintratumorally.

In the various embodiments, the present chimeric protein allows for adual effect that provides less side effects than are seen inconventional immunotherapy (e.g. treatments with one or more of OPDIVO,KEYTRUDA, YERVOY, and TECENTRIQ).

Additionally,pharmacogenomic (the effect of genotype on the pharmacokinetic,pharmacodynamic or efficacy profile of a therapeutic) information abouta particular subject may affect dosage used. Furthermore, the exactindividual dosages can be adjusted somewhat depending on a variety offactors, including the specific combination of the agents beingadministered, the time of administration, the route of administration,the nature of the formulation, the rate of excretion, the particulardisease being treated, the severity of the disorder, and the anatomicallocation of the disorder.

Cells and Nucleic Acids

In various embodiments, the present invention provides an expressionvector, comprising a nucleic acid encoding the chimeric proteindescribed herein. In various embodiments, the expression vectorcomprises DNA or RNA. In various embodiments, the expression vector is amammalian expression vector.

Both prokaryotic and eukaryotic vectors can be used for expression ofthe chimeric protein. Prokaryotic vectors include constructs based on E.coli sequences (see, e.g., Makrides, Microbiol Rev 1996, 60:512-538).Non-limiting examples of regulatory regions that can be used forexpression in E. coli include lac, trp, Ipp, phoA, recA, tac, T3, T7 andλP_(L). Non-limiting examples of prokaryotic expression vectors mayinclude the λgt vector series such as λgt11 (Huynh et al., in “DNACloning Techniques, Vol. I: A Practical Approach,” 1984, (D. Glover,ed.), pp. 49-78, IRL Press, Oxford), and the pET vector series (Studieret al., Methods Enzymol 1990, 185:60-89). Prokaryotic host-vectorsystems cannot perform much of the post-translational processing ofmammalian cells, however. Thus, eukaryotic host-vector systems may beparticularly useful. A variety of regulatory regions can be used forexpression of the chimeric proteins in mammalian host cells. Forexample, the SV40 early and late promoters, the cytomegalovirus (CMV)immediate early promoter, and the Rous sarcoma virus long terminalrepeat (RSV-LTR) promoter can be used. Inducible promoters that may beuseful in mammalian cells include, without limitation, promotersassociated with the metallothionein II gene, mouse mammary tumor virusglucocorticoid responsive long terminal repeats (MMTV-LTR), theβ-interferon gene, and the hsp70 gene (see, Williams et al., Cancer Res1989, 49:2735-42; and Taylor et al., Mol Cell Biol 1990, 10:165-75).Heat shock promoters or stress promoters also may be advantageous fordriving expression of the fusion proteins in recombinant host cells.

In some embodiments, expression vectors of the invention comprise anucleic acid encoding the chimeric proteins (and/or additional agents),or a complement thereof, operably linked to an expression controlregion, or complement thereof, that is functional in a mammalian cell.The expression control region is capable of driving expression of theoperably linked blocking and/or stimulating agent encoding nucleic acidsuch that the blocking and/or stimulating agent is produced in a humancell transformed with the expression vector.

Expression control regions are regulatory polynucleotides (sometimesreferred to herein as elements), such as promoters and enhancers, thatinfluence expression of an operably linked nucleic acid. An expressioncontrol region of an expression vector of the invention is capable ofexpressing operably linked encoding nucleic acid in a human cell. In anembodiment, the cell is a tumor cell. In another embodiment, the cell isa non-tumor cell. In an embodiment, the expression control regionconfers regulatable expression to an operably linked nucleic acid. Asignal (sometimes referred to as a stimulus) can increase or decreaseexpression of a nucleic acid operably linked to such an expressioncontrol region. Such expression control regions that increase expressionin response to a signal are often referred to as inducible. Suchexpression control regions that decrease expression in response to asignal are often referred to as repressible. Typically, the amount ofincrease or decrease conferred by such elements is proportional to theamount of signal present; the greater the amount of signal, the greaterthe increase or decrease in expression.

In an embodiment, the present invention contemplates the use ofinducible promoters capable of effecting high level of expressiontransiently in response to a cue. For example, when in the proximity ofa tumor cell, a cell transformed with an expression vector for thechimeric protein (and/or additional agents) comprising such anexpression control sequence is induced to transiently produce a highlevel of the agent by exposing the transformed cell to an appropriatecue. Illustrative inducible expression control regions include thosecomprising an inducible promoter that is stimulated with a cue such as asmall molecule chemical compound. Particular examples can be found, forexample, in U.S. Pat. Nos. 5,989,910, 5,935,934, 6,015,709, and6,004,941, each of which is incorporated herein by reference in itsentirety.

Expression control regions and locus control regions include full-lengthpromoter sequences, such as native promoter and enhancer elements, aswell as subsequences or polynucleotide variants which retain all or partof full-length or non-variant function. As used herein, the term“functional” and grammatical variants thereof, when used in reference toa nucleic acid sequence, subsequence or fragment, means that thesequence has one or more functions of native nucleic acid sequence(e.g., non-variant or unmodified sequence).

As used herein, “operable linkage” refers to a physical juxtaposition ofthe components so described as to permit them to function in theirintended manner. In the example of an expression control element inoperable linkage with a nucleic acid, the relationship is such that thecontrol element modulates expression of the nucleic acid. Typically, anexpression control region that modulates transcription is juxtaposednear the 5′ end of the transcribed nucleic acid (i.e., “upstream”).Expression control regions can also be located at the 3′ end of thetranscribed sequence (i.e., “downstream”) or within the transcript(e.g., in an intron). Expression control elements can be located at adistance away from the transcribed sequence (e.g., 100 to 500, 500 to1000, 2000 to 5000, or more nucleotides from the nucleic acid). Aspecific example of an expression control element is a promoter, whichis usually located 5′ of the transcribed sequence. Another example of anexpression control element is an enhancer, which can be located 5′ or 3′of the transcribed sequence, or within the transcribed sequence.

Expression systems functional in human cells are well known in the art,and include viral systems. Generally, a promoter functional in a humancell is any DNA sequence capable of binding mammalian RNA polymerase andinitiating the downstream (3′) transcription of a coding sequence intomRNA. A promoter will have a transcription initiating region, which isusually placed proximal to the 5′ end of the coding sequence, andtypically a TATA box located 25-30 base pairs upstream of thetranscription initiation site. The TATA box is thought to direct RNApolymerase II to begin RNA synthesis at the correct site. A promoterwill also typically contain an upstream promoter element (enhancerelement), typically located within 100 to 200 base pairs upstream of theTATA box. An upstream promoter element determines the rate at whichtranscription is initiated and can act in either orientation. Ofparticular use as promoters are the promoters from mammalian viralgenes, since the viral genes are often highly expressed and have a broadhost range. Examples include the SV40 early promoter, mouse mammarytumor virus LTR promoter, adenovirus major late promoter, herpes simplexvirus promoter, and the CMV promoter.

Typically, transcription termination and polyadenylation sequencesrecognized by mammalian cells are regulatory regions located 3′ to thetranslation stop codon and thus, together with the promoter elements,flank the coding sequence. The 3′ terminus of the mature mRNA is formedby site-specific post-translational cleavage and polyadenylation.Examples of transcription terminator and polyadenylation signals includethose derived from SV40. Introns may also be included in expressionconstructs.

There are a variety of techniques available for introducing nucleicacids into viable cells. Techniques suitable for the transfer of nucleicacid into mammalian cells in vitro include the use of liposomes,electroporation, microinjection, cell fusion, polymer-based systems,DEAE-dextran, viral transduction, the calcium phosphate precipitationmethod, etc. For in vivo gene transfer, a number of techniques andreagents may also be used, including liposomes; natural polymer-baseddelivery vehicles, such as chitosan and gelatin; viral vectors are alsosuitable for in vivo transduction. In some situations it is desirable toprovide a targeting agent, such as an antibody or ligand specific for atumor cell surface membrane protein. Where liposomes are employed,proteins which bind to a cell surface membrane protein associated withendocytosis may be used for targeting and/or to facilitate uptake, e.g.,capsid proteins or fragments thereof tropic for a particular cell type,antibodies for proteins which undergo internalization in cycling,proteins that target intracellular localization and enhanceintracellular half-life. The technique of receptor-mediated endocytosisis described, for example, by Wu et al., J. Biol. Chem. 262, 4429-4432(1987); and Wagner et al., Proc. Natl. Acad. Sci. USA 87, 3410-3414(1990).

Where appropriate, gene delivery agents such as, e.g., integrationsequences can also be employed. Numerous integration sequences are knownin the art (see, e.g., Nunes-Duby et al., Nucleic Acids Res. 26:391-406,1998; Sadwoski, J. Bacteriol., 165:341-357, 1986; Bestor, Cell,122(3):322-325, 2005; Plasterk et al., TIG 15:326-332, 1999; Kootstra etal., Ann. Rev. Pharm. Toxicol., 43:413-439, 2003). These includerecombinases and transposases. Examples include Cre (Sternberg andHamilton, J. Mol. Biol., 150:467-486, 1981), lambda (Nash, Nature, 247,543-545, 1974), Flp (Broach, et al., Cell, 29:227-234, 1982), R(Matsuzaki, et al., J. Bacteriology, 172:610-618, 1990), cpC31 (see,e.g., Groth et al., J. Mol. Biol. 335:667-678, 2004), sleeping beauty,transposases of the mariner family (Plasterk et al., supra), andcomponents for integrating viruses such as AAV, retroviruses, andantiviruses having components that provide for virus integration such asthe LTR sequences of retroviruses or lentivirus and the ITR sequences ofAAV (Kootstra et al., Ann. Rev. Pharm. Toxicol., 43:413-439, 2003). Inaddition, direct and targeted genetic integration strategies may be usedto insert nucleic acid sequences encoding the chimeric fusion proteinsincluding CRISPR/CAS9, zinc finger, TALEN, and meganuclease gene-editingtechnologies.

In one aspect, the invention provides expression vectors for theexpression of the chimeric proteins (and/or additional agents) that areviral vectors. Many viral vectors useful for gene therapy are known(see, e.g., Lundstrom, Trends Biotechnol., 21: 1 17, 122, 2003.Illustrative viral vectors include those selected from Antiviruses (LV),retroviruses (RV), adenoviruses (AV), adeno-associated viruses (AAV),and α viruses, though other viral vectors may also be used. For in vivouses, viral vectors that do not integrate into the host genome aresuitable for use, such as α viruses and adenoviruses. Illustrative typesof α viruses include Sindbis virus, Venezuelan equine encephalitis (VEE)virus, and Semliki Forest virus (SFV). For in vitro uses, viral vectorsthat integrate into the host genome are suitable, such as retroviruses,AAV, and Antiviruses. In one embodiment, the invention provides methodsof transducing a human cell in vivo, comprising contacting a solid tumorin vivo with a viral vector of the invention.

In various embodiments, the present invention provides a host cell,comprising the expression vector comprising the chimeric proteindescribed herein.

Useful mammalian host cells include, withoutlimitation, cells derived from humans, monkeys, and rodents (see, forexample, Kriegler in “Gene Transfer and Expression: A LaboratoryManual,” 1990, New York, Freeman & Co.). These include monkey kidneycell lines transformed by SV40 (e.g., COS-7, ATCC CRL 1651); humanembryonic kidney lines (e.g., 293, 293-EBNA, or 293 cells subcloned forgrowth in suspension culture, Graham et al., J Gen Virol 1977, 36:59);baby hamster kidney cells (e.g., BHK, ATCC CCL 10); Chinese hamsterovary-cells-DHFR (e.g., CHO, Urlaub and Chasin, Proc Natl Acad Sci USA1980, 77:4216); DG44 CHO cells, CHO-K1 cells, mouse sertoli cells(Mather, Biol Reprod 1980, 23:243-251); mouse fibroblast cells (e.g.,NIH-3T3), monkey kidney cells (e.g., CV1 ATCC CCL 70); African greenmonkey kidney cells.

EXAMPLES Example 1. Construction and Characterization of MousePD-1-Fc-OX40L Construct

A chimeric mouse PD-1-Fc-OX40L construct was generated and itsexpression in CHO-K1 cells was verified using a mouse IgG capture ELISAassay (here, the Fc is derived from IgG1). Specifically, CHO-K1 cellswere stably nucleofected with pVITRO2-GS-hygro or pcDNA3.4 vectorsexpressing either the mouse extracellular domain (ECD) of PD-1 fused toFc (mPD-1-Fc) or mPD-1-Fc fused to the ECD of OX40L (mPD-1-Fc-OX40L).Antibiotic-resistant single cell clones were isolated via limitingdilution. The concentration of each chimeric protein secreted into theculture media was determined by a mIgG capture ELISA as shown in FIG. 5.

Binding assays were carried out to characterize the ability of mousePD-1-Fc-OX40L to bind to mOX40 as well as to mPD-L1. FIG. 6A, shows aschematic representation of the ELISA assay used to detect binding ofmouse PD-1-Fc-OX40L to mOX40. Specifically, recombinant mOX40 fused tohuman Fc (mOX40-hFc) was used to capture mPD-1-Fc-OX40L in the culturemedia. A rabbit polyclonal antibody to mPD-1 was used to detect themPD-1 domain in the chimeric protein and subsequently detected using ahorseradish peroxidase (HRP)-conjugated polyclonal antibody to rabbitIgG (H+L). FIG. 6B, shows that mouse PD-1-Fc-OX40L efficiently bound toOX40 compared to the mPD-1-Fc negative control. FIG. 7A, shows aschematic representation of the ELISA assay used to detect binding ofmouse PD-1-Fc-OX40L to mPD-L1. Specifically, recombinant mPD-L1 fused tohuman Fc (mPD-L1-hFc) was used to capture the mPD-1-Fc-OX40L chimericprotein in the culture media. A horseradish peroxidase (HRP)-conjugatedpolyclonal antibody to mouse IgG (H+L) was used for the detection of thebound proteins. FIG. 7B, shows that mouse PD-1-Fc-OX40L efficientlybound to PD-L1 as compared to a negative media control and a positivecontrol using recombinant mouse PD1-Fc.

Experiments were carried out to characterize the activity of mousePD-1-Fc-OX40L in eliciting T-cell response and in treating tumors.Chicken ovalbumin antigen-specific OT-I/EGFP, CD8+ T cells (5×10⁵) wereadoptively transferred to C57/BL6-albino mice via tail vein injections 2days prior to inoculation with B16.F10-ova tumor cells (5×10⁵) into theright flank of the mice. Once tumors reached 3-5 mm in diameter,PD-1-Fc-OX40L expressing DNA (50 μg) was electroporated into the tumorusing a defined electrical pulse (1500 V/cm) using 8 pulses at 100 μS.The percentage of CD8+OT-I/EGFP cells in the peripheral blood wasquantified by flow cytometry analysis over the assigned time coursefollowing electroporation. As shown in FIG. 8 , in vivo intratumoraldelivery of mouse (m) PD-1-Fc-OX40L led to an expansion ofantigen-specific CD8+ T-cells.

FIG. 9 shows that the in vivo intratumoral delivery of mPD-1-Fc-OX40Lalso led to tumor regression in the B16.F10-ova tumor model. B16.F10-ovatumors were generated in C57/Bl6-albino mice that were adoptivelytransferred with CD8+OT-I/EGFP cells and electroporated once withmPD-1-Fc-OX40L expressing DNA (50 μg). Control mice did not receive DNAbut were subjected to electroporation (EP only). Tumor diameters weremeasured using a digital caliper over the assigned time course followingelectroporation. FIG. 9 demonstrates that the administration ofmPD-1-Fc-OX40L significantly reduced tumor size.

Example 2. Additional Characterization of Mouse PD-1-Fc-OX40L Construct

A mPD-1-Fc-OX40L construct was generated which included the mouseextracellular domain (ECD) of PD-1 fused to the ECD of OX40L via ahinge-CH2-CH3 Fc domain derived from IgG1 (mPD-1-Fc-OX40L). ThemPD-1-Fc-OX40L construct was transiently expressed in 293 cells andpurified using protein A affinity chromatography. Western blot andfunctional ELISA analysis were performed to validate the detection andbinding of all 3 components of mPD-1-Fc-OX40L (FIG. 10A). Quantitationof mPD1-Fc-OX40L can be assessed using a murine IgG capture anddetection ELISA (FIG. 10B). The binding of mPD-1 and mOX40L to theirpartners mPD-L1 and mOX40, respectively, was demonstrated simultaneouslyby capturing mPD-1-Fc-OX40L with mPD-L1-Fc and detecting it withmOX40-His, followed by His-HRP for chemiluminescence quantitation (FIG.8C). It was also noted that there were monomeric and dimericconformations of mPD-1-Fc-OX40L.

To assess the ex vivo cellular binding of mPD-1-Fc-OX40L, primary mousesplenocytes were isolated and activated for 2 days withPMA/PHA/Ionomycin, in order to up-regulate OX40 and PD-L1 expression.Activated splenocytes were then treated with 500 ng/mL of mPD-1-Fc-OX40Land analyzed by flow cytometry for binding (Fc-PE) (FIG. 8D). To isolatePD-L1 expressing cells, splenocytes were co-stained with an antibodytargeting MHC II on antigen presenting cells (I-A/I-E). To isolate OX40expressing cells, splenocytes were co-stained with CD4. mPD-1-Fc-OX40Lbound significantly to both PD-L1+ and OX40+ populations of splenocytes,indicating that mPD-1-Fc-OX40L had been generated and purifiedcompetently to bind its targets on primary derived cells. The bindingactivity of mPD1-Fc-OX40L to primary mouse tumor cell lines expressingPD-L1 was also assessed. The murine 4T1 tumor cell line was identifiedas expressing low amounts of PD-L1 and the B16.F10 tumor cell lineexpressed comparatively high amounts of PD-L1. mPD1-Fc-OX40L was shownto bind the PD-L1 positive B16.F10 tumor cell line to a greater extentthan the PD-L1 low 4T1 tumor cell line (FIG. 10E).

Additional functional activities of mPD-1-Fc-OX40L were characterizedusing a T cell activation/tumor co-culture assay. First, murinePD-L1_(low) (4T1) and PD-L1_(high) (B16.F10) cells were identified byflow cytometry (FIG. 8E). Next, mouse splenocytes were activated for 2days with CD3/CD28 beads and a sub-saturating concentration of IL2.After 2 days, activated splenocytes were co-cultured with eitherirradiated 4T1 or B16.F10 cells in the presence or absence ofmPD-1-Fc-OX40L. Five days after the initial isolation of splenocytes,culture medium was collected and analyzed for the cytokine IL2 by ELISA(FIG. 8F). It was observed that mPD-1-Fc-OX40L was capable ofsignificant induction of IL2 secretion, especially in co-culturescontaining PD-L1_(high) tumor cells. Without wishing to be bound bytheory, it is believed that mPD-1-Fc-OX40L was concomitantly blockingthe suppressive effects of PD-L1 while also activating T cells viaOX40/OX40L signaling, thereby inducing IL2 secretion. Altogether, thesefindings suggest that mPD-1-Fc-OX40L may provide significant anti-tumorimmunity in pre-clinical models.

The anti-tumor potency of mPD-1-Fc-OX40L was tested using severalpreclinical tumor model systems. Specifically murine models ofcolorectal cancer (CT26 and MC38) were used to assess the effects ofmPD-1-Fc-OX40L on tumor growth, overall survival, and the induction of aserum cytokine response following therapy. These experiments wereperformed head-to-head with extensively characterized OX40 agonist(OX86) and PD-L1 blocking (10F.9G2) antibodies given as monotherapy orin combination, at an equivalent active dose to mPD-1-Fc-OX40L viaintraperitoneal injection (2 doses of 100 ug each). As shown in FIG.11A, mPD-1-Fc-OX40L significantly reduced tumor size in the MC38 model.More particularly, administration of mPD-1-Fc-OX40L resulted in greatertumor regression than the OX40 agonist and PD-L1 blocking antibodiesadministered individually or in combination. Importantly, repeatchallenge of mice that rejected the primary tumor with the parental MC38tumor cell line was performed for each group. These data demonstratedthat, in the absence of repeat treatment, mice treated withmPD1-Fc-OX40L were able to reject a re-challenge with the parental tumorto a greater degree than any of the other treatment groups (FIG. 11A andFIG. 11B). Further, other fusion constructs including mPD1-Fc-GITRL andmPD1-Fc-41BBL were produced and used in tumor bearing mice as describedabove for mPD1-Fc-OX40L. Both the GITRL and 41BBL containing constructsled to reduced tumor size in treated animals.

In addition to measuring tumor size, a pharmacodynamic biomarker formPD-1-Fc-OX40L signaling in vivo was also determined. Specifically, aserum cytokine analysis for mice treated with anti-PD-L1 and anti-OX40antibodies as well as with PD-1-Fc-OX40L was performed. As shown in FIG.11B and FIG. 11C, there was a dose-dependent cytokine signaturefollowing treatment with mPD-1-Fc-OX40L that was remarkably similar tothe cytokine signature observed following combined administration ofanti-PD-L1 and anti-OX40 antibodies, comprising of increased IFNγ, TNFα,IL-2, IL-4, IL-5, IL-6, IL-10, IL-17A and IL-22 (FIGS. 11C, 11D and11J). Importantly, detection of a serum cytokine response followingtreatment with mPD1-Fc-OX40L was shown to be dose dependent.Specifically, treatment with one or two injections of 40 μg did not leadto a detectable serum cytokine response, while treatment with 100 μgonce led to an intermediate cytokine response and treatment with 100 μgtwo times led to a higher cytokine response (FIG. 11K). Treatment ofmice with mPD1-Fc-GITRL was also shown to stimulated a specific serumcytokine response.

In some experiments, mice bearing MC38 tumors were sacrificed on day 13of the experiment to evaluate the cellular immune response in the tumor,peripheral blood and spleen. On day 13 of the experiment, mPD1-Fc-OX40L,mPD1-Fc-GITRL and mCD172a-Fc-CD40L were all shown to cause reduced tumorgrowth as compared to untreated animals or animals treated with OX40agonist antibodies, GITR agonist antibodies or PD-L1 blocking antibodies(FIG. 11E). In accordance with these data, mice treated withmPD1-Fc-OX40L or mPD1-Fc-GITRL were shown to have increased numbers oftumor antigen specific tumor infiltrating lymphocytes (TIL) on day 13 ofthe experiment (FIG. 11F). Analysis of the memory phenotype in thespleen of CD8+ T cells was performed (FIG. 11G) and the CD4/CD8 T cellratio was also compared across multiple treatments (FIG. 11H).

The pharmacodynamic biomarkers for PD-1-Fc-OX40L signaling in vivo wasalso determined using the CT26 model. Specifically, a serum cytokineanalysis for mice treated with anti-PD-L1 and anti-OX40 antibodies,individually or in combination, as well as with PD-1-Fc-OX40L wasperformed. As shown in FIG. 11D, the cytokine signature followingtreatment with mPD-1-Fc-OX40L was remarkably similar to the cytokinesignature observed following the combined administration of anti-PD-L1and anti-OX40 antibodies. Specifically, the cytokine signature comprisedof increased IFNγ, TNFα, IL-2, IL-4, IL-5, IL-6, IL-9, IL-10, IL-13,IL-17A, IL-17F, and IL-22 (FIGS. 11J and 11K).

Consistent with the results derived from the MC38 model, administrationof mPD-1-Fc-OX40L also significantly reduced tumor size in the CT26colorectal cancer model. Particularly, use of mPD-1-Fc-OX40L resulted ingreater tumor regression than the OX40 agonist and PD-L1 blockingantibodies (FIG. 11L). Further, mice administered with mPD-1-Fc-OX40Lexhibited longer survival time than mice administered with the OX40agonist and PD-L1 blocking antibodies (FIG. 11L). In addition, otherchimeric fusion protein constructs including PD1-Fc-GITRL, PD1-Fc-41BBLand PD1-Fc-TL1A were all shown to exhibit delayed tumor growth anregression in the CT26 model (FIG. 11L).

Altogether, these data clearly demonstrate, inter alia, the functionalactivity of mPD-1-Fc-OX40L in vivo.

Accordingly, the amino acid sequence of SL-279252 was as follows:

Alternatively, SL-279252 may include other signaling peptides such asthose derived from human collagen V or human IgG heavy chain.Alternatively, SL-279252 may include one or more mutations in the Fcdomain to increase stability or to increase binding affinity to FcRn,such as those previously described. The human PD-1-Fc-OX40L constructwas imported into the protein tertiary prediction software RaptorX, toensure proper folding of the three major domains (see FIG. 12A). Thetertiary structures of each component (i.e., PD-1, Fc, and OX40L)adopted their native conformations within the larger macromolecule,suggesting that PD-1-Fc-OX40L would retain binding capability andmolecular function of all domains. Next, the immunogenic probability ofPD-1-Fc-OX40L was assessed using an in silico molecular modelingalgorithm, cross-referenced to a T cell epitope database(ABZENA/ANTITOPE, FIG. 12B). Although all coding sequences were human,there was minimal potential for lead and linker sequences to elicit animmune response following treatment. Further analysis was performedusing the iTope antigen prediction technology in silico (ANTITOPE).Based on this analysis, SL-279252 was predicted to have a ‘low-risk’ ofimmunogenicity because no identifiable T cell epitopes were detected.Accordingly, SL-279252 was expected to have low immunogenicity.

The codon-optimized DNA sequence of SL-279252 was then synthesized anddirectionally cloned into pcDNA3.4-hygro-mcs (THERMO FISHER) andpVITRO2-hygro-mcs (INVIVOGEN) expression vectors. Vectors were theneither transiently or stably transfected into CHO-K1 and 293T cells, andculture supernatants were purified using standard protein A agaroseaffinity chromatography. Human Fc/IgG ELISAs on eluted fractions (fromstable transfection experiments) of purified protein show definitivepeaks that align with the first major peak detected from a large-scalepurification obtained from transient transfection experiments (FIG.13A), indicating that successful production of SL-279252 can be achievedusing routine protein purification techniques such as protein A.

To confirm that all three domains of SL-279252 are intact andrecognizable by a protein detection assay, Western blot analysis wasperformed on purified fusion protein probing for human anti-PD-1,anti-Fc, and anti-OX40L (FIG. 13B). SL-279252 was detected by all threeantibodies and when the protein was run under reducing conditions,migrated at approximately 75 kDa. Approximately 50% of the non-reducedprotein ran as a dimer, which was a potential advantage, given the invivo oligomerization associated with OX40/L signaling and function. Thepredicted molecular weight for SL-279252 was 60.3 kDa. The reducedfraction of SL-279252 was detected at a higher molecular weight, which,without wishing to be bound by theory, may be due to glycosylation. Thiswas verified by treating SL-279252 with a protein deglycosylase, PNGaseF (FIG. 13B). Following deglycosylation, the reduced fraction ofSL-279252 migrated exactly at the predicted molecular weight of 60.3kDa. This provided evidence that SL-279252 was co/post-translationallymodified through glycosylation, which played essential roles in theproper folding and stability of proteins, and cell-to-cell adhesion(Dalziel M, Dwek R A. Science 2014, Maverakis E, Lebrilla C B. JAutoimmun. 2015).

Next, analysis was performed to determine whether SL-279252 was able tobind to its receptor/ligand targets using plate-immobilized recombinantproteins in functional ELISA assays. SL-279252 was successfully capturedwith recombinant human OX40 (FIG. 13C), and detected with anti-humanOX40L/anti-goat HRP. In this regard, the capture of SL-279252 with humanOX40, followed by detection with a two-step incubation withgoat-anti-OX40L followed by anti-goat-HRP led to efficient detection. Toestablish whether both ends of SL-279252 could bind their respectivereceptor/ligand simultaneously, another ELISA assay was developed whichcaptures SL-279252 using plate absorbed human PD-L1 and detectsSL-279252 using recombinant OX40-his (FIG. 13D). This assay demonstratesthat SL-279252 can simultaneously bind human PD-L1 and human OX40.

Next, surface plasmon resonance (SPR) analysis was performed todetermine the affinity by which SL-279252 bound to hPD-L1, hPD-L1, hOX40and various human Fc receptors (FIGS. 14A-14O). Specifically,polyhistidine-tagged versions of recombinant human PD-L1, PD-L2 andhuman OX40 was bound to ProteOn HTG tris-NTA chips (BIORAD). SL-279252was then flowed over the bound ligands over a time course and a relativeindex of ‘on-rate’ (Ka) and ‘off-rate’ (Kd) was generated to calculatebinding affinity (K_(D)) of SL-279252 to each partner. Recombinant humanPD-1-Fc and OX40L-Fc were used as positive controls for binding. Thesecontrols have a relatively fast ‘on-rate’ and an equally fast‘off-rate’, resulting in low nanomolar binding affinities. Consistentwith these results, the ‘on-rate’ of SL-279252 to human PD-L1 was rapid,however the ‘off-rate’ was much lower, in fact ˜20-fold slower than the‘off-rate’ of recombinant PD-1-Fc, indicating that SL-279252 boundquickly and stably, with long on-target residence time (FIG. 14A). TheK_(D) of SL-279252 binding to human PD-L1 was calculated to be 2.08 nM,nearly identical to the observed K_(D) of BMS's OPDIVO (˜4 nM). TheK_(D) of SL-279252 binding to human PD-L2 was calculated to be 1.24 nM(FIG. 14B). SL-279252 bound with high affinity to human OX40 (246 pM),again with a fast ‘on-rate’ and slow ‘off-rate’ (FIG. 14C).

To further define the molecular characteristics of SL-279252, SPR wasperformed, analyzing the binding affinities of SL-279252 to chip-bound,Fcγ receptors FcγR1A and to the neonatal receptor, FcRn. The humanimmunoglobulin IgG1 was shown to bind with the highest affinities toFcγR1A, followed by FcRn, in addition to low-level binding to FcγR2b(FIGS. 14C and 14D). SL-279252 did not bind to FcγR1A or FcγR2B, but didbind to FcRn at 73 nM affinity (FIGS. 14D and 14E). Without wishing tobe bound by theory, this binding characteristic may be important to thefusion protein because FcRn is involved in IgG recycling to the surfaceof a cell, thereby avoiding lysosomal degradation, and potentiallyextending the in vivo half-life of SL-279252. Summary data for SL-279252binding affinities are including (FIG. 14F).

Next, surface plasmon resonance (SPR) analysis was performed todetermine the affinity by which a mutated SL-279252 construct containinga collagen V leader peptide and Fc region mutations to increase bindingto FcRn (named colPD1-FcRnOX40L) was examined for binding to hPD-L1,hPD-L1, hOX40 and various human Fc receptors (FIGS. 14A-14O).Specifically, polyhistidine-tagged versions of recombinant human PD-L1,PD-L2 and human OX40 was bound to ProteOn HTG tris-NTA chips (BIORAD).colPD1-FcRnOX40L was then flowed over the bound ligands over a timecourse and a relative index of ‘on-rate’ (Ka) and ‘off-rate’ (Kd) wasgenerated to calculate binding affinity (K_(D)) of colPD1-FcRnOX40L toeach partner. Recombinant human PD-1-Fc and OX40L-Fc were used aspositive controls for binding. These controls have a relatively fast‘on-rate’ and an equally fast ‘off-rate’, resulting in low nanomolarbinding affinities. Consistent with these results, the ‘on-rate’ ofcolPD1-FcRnOX40L to human PD-L1 was rapid, however the ‘off-rate’ wasmuch lower, in fact ˜10-fold slower than the ‘off-rate’ of recombinantPD-1-Fc, indicating that colPD1-FcRnOX40L bound quickly and stably, withlong on-target residence time (FIG. 14G). The K_(D) of colPD1-FcRnOX40Lbinding to human PD-L1 was calculated to be 6.35 nM, nearly identical tothe observed K_(D) of BMS's OPDIVO (˜4 nM). The K_(D) ofcolPD1-FcRnOX40L binding to human PD-L2 was calculated to be 7.93 nM(FIG. 14H). colPD1-FcRnOX40L bound with high affinity to human OX40(9.61 nM), again with a fast ‘on-rate’ and slow ‘off-rate’ (FIG. 14I).

To further define the molecular characteristics of colPD1-FcRnOX40L, SPRwas performed, analyzing the binding affinities of colPD1-FcRnOX40L tochip-bound, Fcγ receptors FcγR1A and to the neonatal receptor, FcRn. Thehuman immunoglobulin IgG1 was shown to bind with the highest affinitiesto FcγR1A, followed by FcRn, in addition to low-level binding to FcγR2b(FIGS. 14J and 14K). colPD1-FcRnOX40L did not bind to FcγR1A or FcγR2B,but did bind to FcRn at 2.51 nM affinity (FIG. 14K). Without wishing tobe bound by theory, this binding characteristic may be important to thefusion protein because FcRn is involved in IgG recycling to the surfaceof a cell, thereby avoiding lysosomal degradation, and potentiallyextending the in vivo half-life of colPD1-FcRnOX40L. Summary data forcolPD1-FcRnOX40L binding affinities are including (FIG. 14L).

Additionally, the in vivo half-life of the purified SL-279252 was testedin C57BL/6 mice by injecting 200 μg of the protein by intra-peritonealinjection. Blood was then collected from treated animals by cardiacpuncture at 10 minutes, 30 minutes, 1 hour, 3, 6, 12 and 24 hours andallowed to clot for 2 hours at room temperature. The serum was thenassayed using a human IgG or OX40L specific ELISA as outlined above. Asshown in FIG. 14M, the serum half-life of SL-279252 in mice following asingle injection of 200 μg of protein was determined to be between 7-15hours. It is anticipated that constructs containing mutations toincrease binding affinity to FcRn will lead to longer half-life in vivo.

The slow off-rates detected by SPR suggested that SL-279252 may have alonger on-target (i.e. intratumoral) half-life than serum half life. Toinvestigate this question, immunocompromised NSG mice were implantedwith a PD-L1 negative HeLa (human cervical cancer) tumor on one flank,and with a PD-L1 expressing HeLa tumor on the opposite flank. Mice weretreated with single injections of 200 μg of SL-279252 and individualmice were sacrificed at defined time points. At the time of sacrifice,both HeLa tumors were excised and bisected. Half of the tumor wasdissociated and analyzed for SL-279252 binding by flow cytometry. Thisanalysis demonstrated that SL-279252 accumulated specifically in PD-L1positive, but not PD-L1 negative tumors. The concentration of SL-279252was observed to increase in the tumor up to 48 hours post treatment(FIG. 14N). Further, immunohistochemical analysis of the other half ofeach tumor demonstrated that significant staining for human OX40L waspresent 5 days post treatment, suggesting that SL-279252 was detectablein PD-L1 positive human tumors at least 5 days following a singletreatment (FIG. 14O).

Example 4. Additional Functional Characterization of Human PD-1-Fc-OX40L

The previous data indicated that SL-279252 binds to immobilized targetsat low nanomolar affinities and was detectable by multiple proteinassays. Additional analysis was carried out to determine whetherSL-279252 could bind its targets on the surface of living cells invitro. To assess SL-279252 binding to the human OX40 receptor, the humanAML T cell line Jurkat was engineered to overexpress OX40, creatingJurkat/hOX40 cells (verified by flow cytometry; FIG. 15A). To assessbinding to PD-L1, the Chinese hamster ovary cell line, CHO-K1, whichdoes not express human PD-L1, was transfected to stably express humanPD-L1 (FIG. 15B). To assess binding to human CD47, CHO-K1 cells weretransfected to stably express human CD47 (FIG. 15C).

CHO-K1 or CHO-K1-PD-L1 cells were then treated with increasing amountsof SL-279252 and analyzed by flow cytometry for the detection of thehuman OX40L domain using anti-human OX40L-APC antibodies. SL-279252 didnot bind to parental CHO-K1 cells since they expressed no detectablehuman PD-L1. However, nearly the entire population of CHO-K1-PD-L1 cellsshifted significantly, indicating that the human PD1 component ofSL-279252 was capable of binding its receptor on living cells (FIG.15D). Jurkat or Jurkat/OX40 cells were then treated with increasingamounts of SL-279252 and analyzed by flow cytometry for detection of thehuman OX40L domain using anti-human OX40L-APC antibodies. SL-279252 didnot bind parental Jurkat cells with high efficiency, since they expresslow amounts of human OX40. However, nearly the entire population ofJurkat/OX40 cells shifted significantly, indicating that the human OX40Lcomponent of SL-279252 was capable of binding its receptor on livingcells (FIG. 15E).

To investigate binding of another chimeric fusion protein, humanCD172a-Fc-OX40L, CHO-K1 or CHO-K1-CD47 cells were then treated withincreasing amounts of CD172a-Fc-OX40L and analyzed by flow cytometry forthe detection of the human OX40L domain using anti-human OX40L-APCantibodies. CD172a-Fc-OX40L did not bind to parental CHO-K1 cells sincethey expressed no detectable human CD47. However, nearly the entirepopulation of CHO-K1-PD-L1 cells shifted significantly, indicating thatthe human CD172a component of CD172a-Fc-OX40L was capable of binding itsreceptor on living cells (FIG. 15F). Jurkat or Jurkat/OX40 cells werethen treated with increasing amounts of CD172a-Fc-OX40L and analyzed byflow cytometry for detection of the human OX40L domain using anti-humanOX40L-APC antibodies. CD172a-Fc-OX40L did not bind parental Jurkat cellswith high efficiency, since they express low amounts of human OX40.However, nearly the entire population of Jurkat/OX40 cells shiftedsignificantly, indicating that the human OX40L component ofCD172a-Fc-OX40L was capable of binding its receptor on living cells(FIG. 15G).

Additionally, a number of human tumor cell lines were screened fordiffering levels of endogenous human PD-L1 expression by flow cytometry.A prostate cancer cell line (PC3) as PD-L1_(low) and a lungadenocarcinoma cell line (HCC827) as PD-L1_(high) were identified (FIG.15H). The PC3 and HCC827 cells were incubated with increasing amounts ofSL-279252, and binding was detected using flow cytometry. SL-279252 didnot bind to PC3 cells (PD-L1_(low)) efficiently (FIG. 15I However,SL-279252 bound significantly to HCC827 cells (PD-L1_(high)) in aconcentration dependent manner (FIG. 15J). This clearly indicated thatSL-279252 could bind both human OX40 and PD-L1 expressed on the cellsurface, which provided compelling evidence for its dual bindingfunctionality.

To expand upon these results, experiments were performed SL-279252binding to primary T cells isolated from peripheral blood mononuclearcells (PBMCs), induced for 2 days ex vivo with a chemical combinationknown to stimulate OX40 expression (phorbol 12-myristate 13-acetate;PMA, phytohemagglutinin; PHA, and lonomycin). As expected, a largeincrease in OX40 expression on CD4+ and CD8+ T cells was observedfollowing PMA/PHA/Ion treatment (FIG. 16A). Binding of SL-279252 to CD4+and CD8+ cells was confirmed using the methods described above (FIG.16B). It was noted that SL-279252 bound efficiently to human T cells(both CD4+ and CD8+).

A T cell activation/IL2 release assay was utilized to assess the extentthat PD-L1 expression on tumor cells inhibited T cell secretion of theanti-tumorigenic cytokine IL2 when the cells were co-cultured (FIG.16C). After 2 days, activated T cells were plated on irradiatedPD-L1_(low) (PC3) and PD-L1_(high) (HCC827) expressing cancer cell linesin the presence or absence of SL-279252. Various readouts of T cellactivation were assessed for up to 1 week following initial T cellisolation, including IL2 secretion (FIG. 16D), proliferation andcytokine expression (FIG. 16E). Baseline levels of IL2 secretion (in theabsence of SL-279252) were significantly higher in PD-L1_(low) PC3co-cultures than with PD-L1_(high) HCC827 cells 6 days after T cellisolation, suggesting that tumor PD-L1 expression either directly orindirectly suppressed the further activation of T cells, as determinedby IL2 secretion (FIG. 16D). The addition of SL-279252 to both PC3 andHCC827 co-cultures increased the IL2 secretion in a concentrationdependent manner. Specifically, the observed increase in IL-2 fromHCC827 co-cultures (PD-L1_(high)) from baseline (no SL-279252) to 5μg/mL of SL-279252 was 1.92-fold, compared to 1.27-fold when co-culturedwith PC3 cells (PD-L1_(low)).

Furthermore, additional characteristics of T cell activation wereanalyzed, including expression of the proliferation marker Ki67 (FIG.16E; top). Co-culture of activated T cells with PD-L1_(high) HCC827cells inhibited proliferation as compared to the level observed in theabsence of HCC827 cells (black line). The addition of SL-279252 to theco-culture increased Ki67 staining in both CD4+ and CD8+ T cells.Moreover, activated T cells expressed higher levels of the cytokinesIFNγ and INFα when co-cultured on HCC827 cells than when T cells werecultured alone, possibly due to the secretion of other stimulatoryfactors by the tumor cells (FIG. 16E; bottom). The expression of thesecytokines increased significantly following treatment with SL-279252.

Altogether these data demonstrate, inter alia, that SL-279252 boundtightly to its partners PD-L1 and OX40 and was able to reverse PD-L1mediated T cell inhibition by PD-L1 positive human tumor cells in vitro.

Example 5. Construction and Characterization of Additional ChimericProteins

Additional constructs were generated which include: additional humanPD-1-Fc-OX40L constructs as well as human hCD172a-Fc-OX40L,hPD1-Fc-TL1A, hBTLA-Fc-OX40L, hTMIGD2-Fc-OX40L, hTIM3-Fc-OX40L,mPD1-Fc-GITRL, mPD1-Fc-41BBL, mPD1-Fc-TL1A, mCD172a-Fc-CD40L,hTIGIT-Fc-OX40L and canine PD-1-Fc-OX40L. Each of these constructs wascodon optimized for expression in Chinese Hamster Ovary (CHO) cells,transfected into CHO cells and individual clones were selected for highexpression. High expressing clones were then used for small-scalemanufacturing in stirred bioreactors in serum-free media and therelevant chimeric fusion proteins were purified with Protein A bindingresin columns. FIG. 17A shows a Western blot characterization of variouschimeric proteins including hCD172a-Fc-OX40L, hPD1-Fc-TL1A,hBTLA-Fc-OX40L, hTMIGD2-Fc-OX40L, hTIM3-Fc-OX40L, mPD1-Fc-GITRL,mPD1-Fc-41BBL, mPD1-Fc-TL1A, mCD172a-Fc-CD40L, hTIGIT-Fc-OX40L.

Binding assays were carried out to characterize the ability of thevarious human ECD-Fc-OX40L constructs to bind to hOX40. With respect tohX_(ECD)-Fc-OX40L, X refers to the ECD of each protein listed in thebracket on the left (with reference to FIG. 17B). FIG. 17B shows aschematic representation of the ELISA method used to detect binding ofhX_(ECD)-Fc-OX40L to hOX40. Recombinant hOX40 fused to human Fc(hOX40-hFc) was used to capture hX_(ECD)-Fc-OX40L in the culture media.Because the hOX40 fusion protein used to capture the target fusionproteins also contains a hIgG region, blocking was performed using anon-HRP conjugated anti-hIgG prior to incubation with the culturesupernatants containing the target fusion proteins. A rabbit polyclonalantibody to hIgG was used to detect the hIgG domain in the chimericprotein and subsequently detected using a horseradish peroxidase(HRP)-conjugated polyclonal antibody to rabbit IgG (H+L).

The binding of SL-279252 to cell surface expressed OX40 on Jurkat cellsby flow cytometry was compared to two negative control proteins whichare not expected to bind human OX40. These data demonstrate thatSL-279252 efficiently binds human OX40 (left panel), while neither humanPD1-Fc-TL1A or canine PD1-Fc-OX40L were observed to bind human OX40(FIG. 17C).

The human CD172a-Fc-OX40L construct was imported into the proteintertiary prediction software RaptorX to determine the tertiarystructure. The predicted tertiary structure is shown in FIG. 17D.

The codon-optimized DNA sequence of several chimeric fusion proteinswere synthesized and directionally cloned into pVITRO2, pcDNA3.4 andother expression vectors. Vectors were then either transiently or stablytransfected into CHO or 293 cells and individual clones were selectedfor high expression. For example, SL-279252 was produced from atransient transfection from 293 cells, purified by affinitychromatography to Protein A columns and evaluated by Coomassie staining,Western blot and quantitated as compared to a BCG standard (FIG. 17E).

In another example, CD172a-Fc-OX40L was produced from a transienttransfection from 293 cells, purified by affinity chromatography toProtein A columns and evaluated by Coomassie staining, Western blot andquantitated as compared to a BCG standard (FIG. 17F). In anotherexample, CD172a-Fc-CD40L was produced from a transient transfection from293 cells, purified by affinity chromatography to Protein A columns andevaluated by the Perkin Elmer LabChip system and quantitated as comparedto a BCG standard (FIG. 17G). In another example, human TIGIT-Fc-OX40Lwas produced from a transient transfection from 293 cells, purified byaffinity chromatography to Protein A columns and evaluated by Coomassiestaining, Western blot and quantitated as compared to a BCG standard(FIG. 17H).

The binding affinity of human CD172a-Fc-OX40L was evaluated by surfaceplasmon resonance (SPR) analysis to hCD47, hOX40 and various human Fcreceptors (FIGS. 17I-17M). Specifically, polyhistidine-tagged versionsof recombinant human CD47 and human OX40 was bound to ProteOn HTGtris-NTA chips (BIORAD). CD172a-Fc-OX40L was then flowed over the boundligands over a time course and a relative index of ‘on-rate’ (Ka) and‘off-rate’ (Kd) was generated to calculate binding affinity (K_(D)) ofCD172a-Fc-OX40L to each partner. Recombinant human CD47-Fc and OX40L-Fcwere used as positive controls for binding. These controls have arelatively fast ‘on-rate’ and an equally fast ‘off-rate’, resulting inlow nanomolar binding affinities. Consistent with these results, the‘on-rate’ of CD172a-Fc-OX40L to human CD47 was rapid, however the‘off-rate’ was much lower, in fact ˜40-fold slower than the ‘off-rate’of recombinant CD47-Fc, indicating that CD172a-Fc-OX40L bound quicklyand stably, with long on-target residence time (FIG. 17I). The K_(D) ofCD172a-Fc-OX40L binding to human CD47 was calculated to be 3.59 nM.CD172a-Fc-OX40L bound with high affinity to human OX40 (869 pM), againwith a fast ‘on-rate’ and slow ‘off-rate’ (FIG. 17J).

To further define the molecular characteristics of CD172a-Fc-OX40L, SPRwas performed, analyzing the binding affinities of CD172a-Fc-OX40L tochip-bound, Fcγ receptors FcγR1A and to the neonatal receptor, FcRn. Thehuman immunoglobulin IgG1 was shown to bind with the highest affinitiesto FcγR1A, followed by FcRn, in addition to low-level binding to FcγR2b(FIGS. 17K and 17L). CD172a-Fc-OX40L did not bind to FcγR1A or FcγR2B,but did bind to FcRn at 790 nM affinity (FIG. 17L). Without wishing tobe bound by theory, this binding characteristic may be important to thefusion protein because FcRn is involved in IgG recycling to the surfaceof a cell, thereby avoiding lysosomal degradation, and potentiallyextending the in vivo half-life of CD172a-Fc-OX40L. Summary data forCD172a-Fc-OX40L binding affinities are including (FIG. 17M).

The codon-optimized DNA sequence of several additional chimeric fusionproteins were synthesized and directionally cloned into pVITRO2,pcDNA3.4 and other expression vectors. Vectors were then eithertransiently or stably transfected into CHO or 293 cells and individualclones were selected for high expression. For example, caninePD1-Fc-OX40L was produced from a transient transfection from 293 cells,purified by affinity chromatography to Protein A columns and evaluatedby Coomassie staining, Western blot and quantitated as compared to a BCGstandard (FIG. 17N). In another example, mouse PD1-Fc-OX40L was producedfrom a transient transfection from 293 cells, purified by affinitychromatography to Protein A columns and evaluated by Coomassie staining,Western blot and quantitated as compared to a BCG standard (FIG. 17O).In another example, mouse PD1-Fc-GITRL was produced from a transienttransfection from 293 cells, purified by affinity chromatography toProtein A columns and evaluated by Coomassie staining, Western blot andquantitated as compared to a BCG standard (FIG. 17P). In anotherexample, mouse PD1-Fc-41BBL was produced from a transient transfectionfrom 293 cells, purified by affinity chromatography to Protein A columnsand evaluated by Coomassie staining, Western blot and quantitated ascompared to a BCG standard (FIG. 17Q). In another example, mousePD1-Fc-TL1A was produced from a transient transfection from 293 cells,purified by affinity chromatography to Protein A columns and evaluatedby Coomassie staining, Western blot and quantitated as compared to a BCGstandard (FIG. 17R). In yet another example, CD115-Fc-CD40L was producedfrom a transient transfection from 293 cells, purified by affinitychromatography to Protein A columns and evaluated by Coomassie staining,Western blot and quantitated as compared to a BCG standard (FIG. 17S).

Each purified protein is characterized by ELISA assays to bind to themarker, e.g. the intended inhibitory ligand as well as the intendedcostimulatory receptor. For example, to test the binding of purifiedhuman PD-1-Fc-OX40L, recombinant PD-L1-Fc is adsorbed to microtiterplates and used to capture PD-1-Fc-OX40L. Any bound PD-1-Fc-OX40L isthen detected by using recombinant human OX40-Fc linked to biotin, whichis then detected in a chromogenic assay through binding withstreptavidin-HRP.

In addition, each purified protein has been characterized by flowcytometry to bind the intended inhibitory ligand as well as the intendedcostimulatory receptor. For example, human tumor cell lines arecharacterized for endogenous expression of PD-L1, which was found to beparticularly abundant on several human melanoma tumor cell lines. Thesesame tumor cell lines were shown to be negative for human OX40L.Following incubation with PD-1-Fc-OX40L, any bound chimeric fusionprotein is detected with human OX40L specific antibodies. Similarly,human Jurkat cells were transfected with human OX40 and shown to benegative for human PD-L1. Following incubation with the chimericPD-1-Fc-OX40L constructs, any bound complex is detected using anti-humanPD-L1 specific antibodies. A series of screening cell lines weregenerated in order to detect specific cell surface binding of eachchimeric fusion protein to its respective receptor/ligand, theseincluded: CHO-K1-CD47, CHO-K1-PD-L1, CHO-K1-HVEM, CHO-K1-HHLA2,CHO-K1-VISTA, CHO-K1-Gal9, HeLa-PD-L1, HeLa-CD47, HeLa-HVEM, HeLa-HHLA2,HeLa-VISTA, HeLa-Gal9.

To determine the functional activity of each receptor, in vitro T cellproliferation assays are performed in the presence of inhibitory ligandpositive human tumor cells. For example, human melanoma tumor cellsexpressing PD-L1 are pulsed with peptides specific for hen egg lysozyme(HEL) and incubated with human HEL specific T cells expressing OX40receptor. The proliferation of these cells is monitored in the presenceand absence of the PD-1-Fc-OX40L construct and found to be functionallyresponsive to the presence of the chimeric constructs. In a similarsystem, human tumors expressing HVEM, CD47, galectin-9, TIGIT receptorsor TMIGD2 receptors are used.

In some experiments, mouse PD-1-Fc-OX40L or mouse PD-1-Fc-TL1A are usedto treat murine tumors known to be positive for murine PD-L1 (includingB16-F10 melanoma, MC38 colon carcinoma and CT26 colon carcinoma). Inthese systems, established tumors are treated with purified chimericfusion proteins as compared to PD-1-Fc fusion proteins, anti-PD-1 oranti-PD-L1 monoclonal antibodies or anti-OX40 or anti-GITR monoclonalantibodies. In these experiments, the activity of the chimericconstructs is observed to lead to enhanced antigen-specific T cellresponses and increased rates of tumor rejection as compared to theindividual therapeutics. In some experiments, nucleic acid constructsencoding PD-1-Fc-OX40L or PD-1-Fc-TL1A are directly electroporated intoestablished tumors. In these experiments, the chimeric constructs areshown to lead to increased rates of tumor rejection as well as increasedtumor antigen specific CD8+ T cell proliferation detected both in theperipheral blood and within established tumors.

To determine the binding of purified chimeric fusion proteins to humantumor explants, fresh frozen human tumor samples are obtained andincubated with each chimeric fusion protein. Any bound fusion protein isdetected with anti-human OX40L and controlled against backgroundstaining by separate staining with anti-human OX40L.

To determine the molecular characteristics of each fusion protein,purified chimeric fusion proteins are characterized by size exclusionchromatography. This analysis is important because, for example, theOX40L ECD is known to form a homo-trimer, while the Fc region is knownto form a homo-dimer, while the inhibitory ligand binding receptor mayeither be monomeric (e.g. PD-1) or form homo-multimers (e.g. TIM3).Thus, there are several possibilities for the individual species thatmay be formed by these chimeric constructs. Further molecularcharacterization by mass spec, thermal stability, pH stability, physicalstability, charge profile, hydrophobicity, physical stability, buffercompatibility and solubility up to 100 mg/mL are also performed.
